In a series LCR circuit, $C = 80 μF, L = 5.0 H$ and $R = 40 Ω$ are connected to a variable frequency source of 240 V. The angular frequency of the source which drives the circuit at resonance will be |
$5\, rad\, s^{-1}$ $25\, rad\, s^{-1}$ $0.05\, rad\, s^{-1}$ $50\, rad\, s^{-1}$ |
$50\, rad\, s^{-1}$ |
The correct answer is Option (4) → $50\, rad\, s^{-1}$ |
